Start with PyPI, also known as the CheeseShop.

http://pypi.python.org/pypi

It's not quite as powerful as Perl's CPAN, but it's still pretty good.

Then follow up with Google and other search engines. I prefer Duck Duck Go 
because they don't track you and they take privacy seriously:


http://duckduckgo.com/

Also they have dedicated syntax for searching for Python related information.

Finally, ask on Python forums, particularly the comp.lang.python newsgroup 
(also available as python-l...@python.org) which is more general than this 
email list. This list is more specialised for learning Python the language.

No built-in, but take a look at

the SAGE project, which is an open-source alterative to Magma / Maple / 
Mathematica / Matlab:
http://www.sagemath.org/
Sage is a funky, through-the-web console that uses Python to drive lots of math 
software. Note that there's a public server so you can easily take it for a 
spin:

It sure looks like there is:
https://www.google.com/search?q=Factor+analysis+python&ie=utf-8&oe=utf-8&client=ubuntu&channel=fs

It looks like MDP might do what you need

[Tutor] Factor Analysis

2012-07-05 Thread Ali Torkamani
Dear Tutors,

Two quick questions:

1) Specifically, is there any built-in function for factor analysis is
python?

2) Generally how would you search, to find out if there exist an efficient
python package for some specific task? (Google search usually results in
many hardly-related *false* positives!)

Thanks a bunch!
